How to use an Arduino as a USB to TTL converter || Arduino tutorial

This short video is a tutorial on how to use an Arduino as a USB to TTL (also known as COM or RS-232) converter. I was using a dedicated converter bought from eBay in my previous video:    • How to unbrick a TP-Link TL-WR1043ND route...  . If you have an Arduino lying around, it will easily substitute a USB to TTL converter.
